DBS 270 DBS 270-140, 1Ph 230 V 50/60 Hz

Atlas Copco DBS 270 – single-stage side channel blower with single impeller

Depending on the model, the DBS 270 delivers up to 270 m³/h at 50 Hz and up to 330 m³/h at 60 Hz. According to the data sheet, it reaches down to −220 mbar in vacuum operation and up to +230 mbar in compressor operation. The motor power is 1.5–2.55 kW (IE3). Dimensions up to 340 × 370 × 337 mm (L × W × H), weight 25.3–26 kg, inlet and outlet G 2" (DN 50). Atlas Copco marks the data sheets of the models with part number 8055810… as preliminary (as of 09/2024).

Oil-free side channel principle

According to Atlas Copco, the DBS range with single impeller is suitable for volume flows up to 1370 m³/h at a vacuum of up to −360 mbar (50 Hz). The impeller accelerates the air in the side channels without contact; there is no oil, no oil filter and no exhaust filter, and the exhaust air stays clean.

Applications of the range

Atlas Copco lists, among others, pad printing, paper cutting, roller cleaning, yarn processing, pneumatic conveying, vacuum tables, drying, the extraction of condensate, paint mist, chips and dust, and waste water treatment.
